Abstract
The invention discloses a stroke adjustable engineering hydraulic cylinder which comprises a cylinder body, a front cylinder cover, a rear cylinder cover, a piston rod and a piston, wherein the piston rod and the piston are arranged in the cylinder body; the piston is arranged at the tail end of the piston rod; a transmission plate is arranged at the front end of the piston rod and connected with equipment to be transmitted; and the stroke adjustable engineering hydraulic cylinder is characterized in that an adjusting section extending outwards is arranged at the front end of the piston rod; an adjusting thread and a locking nut matched with the adjusting thread are arranged on the adjusting section; and the transmission plate is screwed on the adjusting section. According to the stroke adjustable engineering hydraulic cylinder, the adjusting section and the locking nut are arranged, the position of the transmission plate is adjusted, and the locking nut performs locking, so that the demands on different transmission connecting positions can be met without changing the internal structure of the cylinder body; and the stroke adjustable engineering hydraulic cylinder can is convenient and flexible to use.
Description
Technical field
The present invention relates to a kind of hydraulic jack, particularly a kind of range-adjustable engineering hydraulic jack.
Background technique
Oil hydraulic cylinder with hydraulic pressure can change mechanical energy into, the do straight reciprocating motion hydraulic actuator of (or oscillating motion).Its simple in structure, reliable operation.When realizing to-and-fro motion with it, can remove speed reducer from, and not have drive gap, therefore motion steadily is widely used in the hydraulic system of various machineries.Oil hydraulic cylinder is divided into piston type, plunger type, swing type and telescopic by structure type, wherein uses at most with piston-type hydraulic cylinder.
Piston-type hydraulic cylinder is made up of cylinder barrel, piston, piston rod, forward and backward cylinder cap etc. usually; Piston sleeve is located at the piston rod tail end, and driver plate is connected with the front end of piston rod, is connected with the device of treating transmission by driver plate; Therefore, the distance of transmission is the stroke of piston rod movement.Yet in actual use, the client needs the connection distance of oil cylinder adjustable sometimes, all can realize the transmission to device between a certain distance regions, so require oil cylinder transmission distance variable, and cylinder interior does not change.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: a kind of range-adjustable engineering hydraulic jack through the improvement of structure, makes cylinder body transmission journey variable, and need not to change the cylinder interior structure.
Technical solution of the present invention is achieved in that a kind of range-adjustable engineering hydraulic jack; Comprise cylinder body, forward and backward cylinder cap, and be arranged at piston rod and the piston in this cylinder body; Said piston is arranged at the tail end of said piston rod; The front end of said piston rod is provided with driver plate, and this driver plate is connected with the equipment of treating transmission, and said piston rod front end is provided with outward extending adjusting section; This adjusting section be provided with regulate screw thread and with the locking nut of this adjustings screw-thread fit, said driver plate is bolted in the said adjusting section.
In the technique scheme, said length of regulating section treats that with hydraulic jack adjustable range matches.
When prolonging adjusting, driver plate is turned to regulating the section outside along regulating screw thread, then locking nut is tightened driver plate and device assembles to be connected to the driver plate side; When shorten regulating, earlier locking nut is turned to the cylinder body side, then with driver plate to the locking nut side shifting, after device location to be connected is corresponding, locking nut is tightened to the driver plate side.Regulating moving on the section, adapt to the needs of different device locations to be connected through driver plate.
Because the utilization of technique scheme, the present invention compared with prior art has advantage: the present invention is provided with at piston rod front end extend outwards and regulates section, regulates on the section outside thread is set; On the adjusting section, be provided with locking nut; Driver plate is bolted in to be regulated on the section, and when needs were adjusted the position of driver plate and equipment to be connected, driver plate moved along regulating section; After putting in place locking nut is locked driver plate; Thereby adapt to the connection needs of different device locations to be connected, and need not to change the hydraulic jack internal structure, easy to use, flexible.
Description of drawings
Below in conjunction with accompanying drawing technological scheme of the present invention is described further:

Fig. 2 is the user mode figure of the embodiment of the invention one.
Wherein: 1, cylinder body; 2, front end housing; 3, back cylinder cover; 4, piston rod; 5, piston; 6, driver plate; 7, regulate screw thread; 8, locking nut.
Embodiment
Below in conjunction with accompanying drawing the present invention is described.
Be depicted as a kind of range-adjustable engineering hydraulic jack of the present invention like Fig. 1,2, comprise cylinder body 1, front end housing 2, back cylinder cover 3; And be arranged at the piston rod 4 and piston 5 in this cylinder body 1; Said piston 5 is arranged at the tail end of said piston rod 4, and the front end of said piston rod 4 is provided with driver plate 6, and this driver plate 6 is connected with the equipment of treating transmission; Said piston rod 4 front ends are provided with outward extending adjusting section; This adjusting section is provided with the locking nut 8 of regulating screw thread 7 and cooperating with this adjusting screw thread 7, and said driver plate 6 is bolted on the said adjusting section, and said length of regulating section treats that with hydraulic jack adjustable range matches.
In the present embodiment, as shown in Figure 2, the distance that needs to regulate is 750.5 ㎜～763.5 ㎜; When prolonging adjusting, driver plate 6 is turned along regulating screw threads 7 (left side) outside regulating section, after putting in place; Locking screw 8 mothers are tightened driver plate 6 and device assembles to be connected to driver plate 6 sides; When shorten regulating, earlier locking nut 8 is turned to cylinder body 1 side (right side), then with driver plate 6 to locking nut 8 side shiftings, after device location to be connected is corresponding, locking nut 8 is tightened to driver plate 6 sides., adapt to the needs of different device locations to be connected, and need not to change cylinder body 1 internal structure regulating moving on the section through driver plate 6.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
